Abstract

The invention provides an aqueous epoxy bonding agent for a carpet bituminous mixture pavement. The aqueous epoxy bonding agent comprises a component A, a component B and water, wherein the component A contains aqueous epoxy resin with solid content of 50 to 100%, the component B is an aqueous epoxy hardener with solid content of 30 to 70%, and the weight ratios of the aqueous epoxy resin, the aqueous epoxy hardener and water are 100 parts, 100 to 200 parts and 0 to 500 parts, respectively. The aqueous epoxy bonding agent provided by the invention has the characteristics of good fluidity, adjustable curing speed and no pollution, can be prepared on a construction site and can be easily sprayed on a curled bituminous material; through controlling of appropriate process conditions during construction, the obtained bituminous pavement has the advantages of good mechanical strength and small possibility of damage; and the construction can be carried out at room temperature and a minimum construction temperature can reach 0 DEG C.

Description

technical field [0001] The invention belongs to the field of road engineering, and in particular relates to an adhesive containing a polymer compound and a construction method thereof. Background technique [0002] With the rapid development of the national economy, the construction scale of expressways in our country has grown rapidly. At present, our country has become the second largest country with high-grade highways in the world. The highways built in the early days were restricted by the economic level and technical level, resulting in many ruts and serious damage on the road surface, which greatly reduced the transportation efficiency and service level of the highway. And one after another a number of high-grade highways will enter the maintenance period. Carpet pavement breaks through the concept of traditional asphalt pavement construction and overlay repair, and introduces the concept of rollable pavement, and the pavement can be prefabricated and repaired in the...
